Abstract
We report a 22-year-old woman who developed systemic lupus erythematosus (SLE) immediately after an Epstein-Barr virus (EBV)-induced mononucleosis infection. The link between these two conditions has long been suspected. The close temporal relationship, the course of the pathological events and the development of immunological changes in this case provide further evidence supporting the hypothesis that EBV infection could work as a trigger in some cases of SLE, particularly if the patient is genetically susceptible.

Abstract
Over the past decade there have been several reports in the literature of atypical forms of granuloma annulare (GA) occurring in HIV positive patients. We now report a case of diffuse granuloma annulare in an HIV positive patient with unusual clinical and immunohistological features. Our patient presented with a persistent extensive macular erythematous eruption on his face and upper trunk with bizarre sparing around the nipples and axillae. The histology showed an interstitial pattern of GA, with a predominance of CD8 positive cells, in contrast to the usual CD4 positive infiltrate typically seen in GA.

Abstract
Normal human skin is remarkably resistant to infection from the large numbers of microorganisms that routinely colonize its surface. In addition to the role of skin as a mechanical barrier, it has long been recognized that skin and other epithelia can produce a range of anti-microbial chemicals that play an important part in eliminating potential cutaneous pathogens. Anti-microbial peptides are an important evolutionarily conserved innate host defense mechanism in many organisms. Human beta defensin-1 and -2 are cysteine-rich, cationic, low molecular weight anti-microbial peptides that have recently been shown to be expressed in epithelial tissues. In this study, we describe the characterization of human beta defensin-1 and -2 mRNA and peptide expression in normal human skin. Using reverse transcription-polymerase chain reaction we demonstrate that human beta defensin-1 is consistently expressed in skin samples from various body sites. Human beta defensin-2 demonstrates expression that is more variable and is more readily detectable in facial skin and foreskin compared with skin from abdomen and breast. In situ hybridization localizes the human beta defensin-1 and -2 transcripts to keratinocytes within interfollicular skin. Using specific antibodies, we have shown that human beta defensin-1 and -2 peptides are localized to the Malpighian layer of the epidermis and/or stratum corneum and that there are interindividual and site-specific differences in intensity of immunostaining and the pattern of peptide localization. The localization of human beta defensins to the outer layer of the skin is consistent with the hypothesis that human beta defensins play an essential part in cutaneous innate immunity.

Abstract
Low concordance in grading atypical (dysplastic) melanocytic nevi (AMN) has been reported, and no systematic evaluation is available. We studied 123 AMN with architectural and cytologic atypia (40 associated with atypical-mole syndrome), classified according to standard criteria by 3 independent observers. Histologic variables included junctional and dermal symmetry, lateral extension, cohesion and migration of epidermal melanocytes, maturation, regression, nuclear features, nuclear grade, melanin, inflammatory infiltrate location, and fibroplasia. AMN (43 junctional and 80 compound) were graded mild (31), moderate (61), and severe (31). AMN-severe correlated with 3 or more nuclear abnormalities (especially pleomorphism, heterogeneous chromatin, and prominent nucleolus) and absence of regression, mixed junctional pattern, and suprabasilar melanocytes on top of lentiginous hyperplasia. AMN-severe diagnostic accuracy was 99.5% using these criteria, but only the absence of nuclear pleomorphism differentiated AMN-mild from AMN-moderate. No architectural features distinguishing AMN-mild from AMN-moderate were selected as significant by the discriminant analysis. AMN from atypical-mole syndrome revealed subtle architectural differences, but none were statistically significant in the discriminant analysis. Histologic criteria can reliably distinguish AMN-severe but fail to differentiate AMN-mild from AMN-moderate. AMN from atypical-mole syndrome cannot be diagnosed using pathologic criteria alone.

Abstract
Sebaceous carcinomas are rare cutaneous appendageal tumors that may occur sporadically or in association with an internal malignancy in Muir-Torre syndrome. In Muir-Torre syndrome microsatellite instability can often be demonstrated in tumor DNA as a result of an inherited mutation in one of several known mismatch repair genes; however, the role of microsatellite instability in sporadic sebaceous carcinomas has not been previously studied. In this report we describe the clinicopathologic characteristics of a series of unselected sebaceous carcinomas and examine them for the presence of microsatellite instability. Of 10 consecutive tumors identified over a 10 y period, only one was from a patient known to have Muir-Torre syndrome. Of the nine presumed sporadic cases, five were from four renal transplant recipients and four from otherwise healthy individuals. Microsatellite instability was demonstrable in three cases: in the Muir-Torre syndrome-associated tumor and in two tumors from transplant patients. Microsatellite instability was subsequently also found in a sebaceous carcinoma from a further transplant patient prospectively sought from another institution. The presence of microsatellite instability in post-transplant sebaceous carcinomas was associated with loss of expression of the mismatch repair protein hMSH2. In summary, sebaceous gland carcinomas, while characteristic of Muir-Torre syndrome, are commonly found outside this context. Among presumed sporadic cases, our data suggest they may be over-represented in immunosuppressed renal transplant recipients. The presence of microsatellite instability in transplant-associated lesions, together with loss of hMSH2 expression suggests that immunosuppression might unmask a previously silent Muir-Torre syndrome phenotype in some cases. Alternatively, there is experimental evidence to suggest that immunosuppressive drugs, most plausibly azathioprine, could select for the emergence of a mutator phenotype and thus predispose to the development of sebaceous carcinomas. The role of mismatch repair defects in other post-transplant skin malignancies remains to be established.

Abstract
BACKGROUND Tinea capitis is a common childhood infection that has recently become more frequent in urban areas in Europe and the U.S.A. The current licensed treatment in children is griseofulvin 10 mg kg(-1) daily, which is usually given for 6--8 weeks. OBJECTIVES To compare this treatment with a 4-week course of oral terbinafine. METHODS Terbinafine was given at the following doses: in children weighing < 20 kg, 62.5 mg daily; 20--40 kg, 125 mg daily; > 40 kg, 250 mg daily. Two hundred and ten children aged 2--16 years, with mycologically confirmed tinea capitis, were randomized to 4 weeks treatment with terbinafine or 8 weeks with griseofulvin, and followed for a total of 24 weeks to determine the difference between treatments with respect to short- and long-term efficacy and tolerability. RESULTS One hundred and forty-seven patients were evaluable (terbinafine 77, griseofulvin 70). Although the 4-week course of terbinafine resulted in a trend to more rapid clearance of tinea capitis, there were no statistically significant differences between the two drugs in terms of overall outcome or tolerability, apart from in a subgroup of patients with Trichophyton infections, and weighing > 20 kg, who responded better to terbinafine than to griseofulvin at 4 weeks. By contrast, there was a better response to griseofulvin than to terbinafine in patients with Microsporum audouinii infections. CONCLUSIONS Overall, the study showed that 4 weeks of treatment with oral terbinafine has similar efficacy to 8 weeks of treatment with griseofulvin for the management of tinea capitis in children.

Abstract
Ruby laser-assisted hair removal is thought to act via selective photothermolysis of melanin in the hair follicles. Although initial clinical trials of permanent hair removal using ruby lasers are promising, the exact mechanisms of hair destruction and the potential damage to other structures of skin are not known. The aim of this study was to evaluate the cutaneous ultrastructural changes following ruby laser hair removal. Nineteen healthy Caucasian patients with dark (brown/black) hair were treated with the ruby laser and biopsies taken after 0, 2, 3, 5, 7, 14 and 21 days. Specimens were examined by light and electron microscopy. Laser-treated specimens showed widespread coagulation and charring of subcutaneous hair shafts. These obviously damaged follicles were randomly dispersed amongst intact follicles within the same treatment sites. Microscopic changes were also seen in the basal epidermis where melanin was concentrated, irrespective of any obvious macroscopic damage. A low level of inflammatory response seen up to 2 weeks after treatment always followed laser treatment. Suprabasal epidermal necrosis was only seen in patients with blister formation after treatment. Ruby laser irradiation results in selective damage to the hair follicles, with microscopic changes to the basal epidermis. The damage is probably compounded by the inflammatory response to the damaged hair. The normal appearance and distribution of collagen in the dermal layer supported the clinical evidence that laser-assisted hair removal, if performed correctly, does not lead to scar formation.

Abstract
Long-term immunosuppressive drug regimes, used to prevent organ transplant rejection, are associated with an increased risk of epithelial malignancies particularly anogenital and cutaneous cancers. Premalignant and malignant lesions of the oral mucosa have also been reported in renal transplant recipients (RTRs), particularly of sun-exposed lip lesions. Many of these anogenital lesions are associated with the detection of high-risk mucosal human papillomaviruses (HPV). Novel degenerate and nested polymerase chain reaction (PCR) techniques have found high levels of epidermodysplasia verruciformis (EV) HPVs (high-risk cutaneous oncogenic HPVs) in cutaneous warts, dysplastic keratoses, and squamous cell carcinomas. Unusual appendageal and spindle cell carcinomas are being observed in RTRs. Increasing survival times of HIV-positive patients may be associated with dysplasia of orogenital mucosal epithelium, and careful epidemiologic studies of cutaneous lesions are needed. The role of HPVs in the development of these lesions has yet to be established.

Abstract
A 30-year-old Chinese man presented with a 2-month history of enlarging neck masses and a widespread rash. He had first noticed the swellings 10 years ago when a diagnosis of tuberculosis was made. The lymphadenopathy improved after anti-tuberculous therapy but never completely regressed. Seven years later, a skin eruption developed over his limbs and trunk. He described recurring crops of asymptomatic reddish papules which discharged a yellowish fluid and subsequently healed with scarring and hyperpigmentation. There was no pruritus or tenderness and no pulmonary symptoms. Clinical examination revealed a non-tender, 10 cm, firm and ovoid mass with overlying erythema in the right anterior triangle of his neck (Figure 1) with several smaller lumps on the other side. There was a widespread eruption on his trunk and limbs, sparing the face, palms, sole and scalp (Figure 2). Recent lesions consisted of 1cm erythematous papules with a scaly collarette (Figure 3). Older lesions had left atrophic scarring and hyperpigmentation. A clinical diagnosis of papulonecrotic tuberculide was made. An X-ray of the chest was normal. Serum immunoglobulins (IgG, A and M) were moderately elevated. Erythrocyte sedimentation rate and C-reactive protein level were normal. Syphilis serology was negative. A Heaf test was strongly positive (Figure 4). Fine needle aspirations of the neck mass were negative for microscopic identification of acid-fast bacilli and for malignancy. On the other hand, a lymph node biopsy on the left side revealed fragments of connective tissue showing granulomatous inflammation and non-caseating necrosis. Occasional acid-fast bacilli were seen with a Ziehl-Neelsen stain. Skin biopsies were taken of recent, established and old lesions. The histological features of the established lesion were diagnostic, showing a florid, acute on chronic, perivascular and periappendiceal inflammmatory infiltrate involving both the superficial and deep dermis. There was also evidence of lobular panniculitis with fibrinoid necrosis of medium-sized arterial vessels, venulitis and extensive endothelial cell swelling. Histological features of the other two skin specimens were non-specific. No organisms were identified with special stains. Anti-tuberculous therapy with rifampicin, isoniazid and pyrazinamide was started and 2 weeks after treatment, the patient reported a complete cessation in the development of new skin lesions. His skin remains in remission after 6 weeks of treatment.

Abstract
Infantile myofibromatosis (IM) is a distinct but rare clinicopathological entity occurring in neonates and infants. It probably represents a rare soft-tissue tumour made up of undifferentiated myofibroblasts. Its recognition is important since it can be mistaken for a malignancy when, in fact, it has a generally benign prognosis with spontaneous regression. We describe the first case of an infant with IM presenting with acute intussusception due to gastrointestinal as well as the typical skin involvement.

Abstract
The clinical and histological effects of retinyl propionate cream (a retinyl ester) on extrinsic skin ageing (photo-ageing) in man were assessed in a double-blind randomized placebo-controlled study of 80 subjects, individual parameters of this being assessed for each treatment site (face, dorsal right forearm and hand, dorsal left forearm and hand) at intervals throughout the study, while skin surface replicas from sites of fine wrinkling around the eye and skin biopsies from the dorsal right forearm were also regularly reviewed throughout. Seventy-five subjects completed an initial 24-week study period, following which 60 elected to continue for a further 24 weeks. Although minimal trends towards improvement occurred, no statistically significant differences between the effects of the retinyl propionate cream and the placebo preparation were apparent for any of the clinical, histological or profilometric parameters of skin photoageing; however, in the very few subjects affected, actinic keratoses in the active group were reduced virtually to zero by week 48.

Abstract
We present two fatal cases of cytophagic panniculitis (CP) and haemophagocytic syndrome (HPS). In the first of these, there was an underlying T-cell lymphoma but in the second no associated disease was found. HPS is a frequently fatal disorder of immune regulation, characterized by fever, histiocytic haemophagocytosis, hepatosplenomegaly, pancytopenia, hypertriglyceridaemia and coagulopathy; CP is a less common manifestation. A number of benign and malignant conditions may present with HPS, the clinical findings and investigations aiding in determining an underlying disorder. Therapy is both supportive and directed at any associated illness, but often very difficult as diagnosis is delayed.

Abstract
Kaposi's sarcoma may occur in transplant recipients on immunosuppressive regimens, but is not well recognized in association with treatment for dermatological disease. We report two cases where multifocal Kaposi's sarcoma developed following iatrogenic immunosuppression with prednisolone and azathioprine for bullous pemphigoid. Both patients were HIV negative and, in one case, lesions regressed both clinically and histologically when immunosuppressive therapy was withdrawn.

Abstract
Based on our series of 111 cases of non-Langerhans cell histiocytoses, we present a new unifying concept for this rare group of disorders. The common denominator is the monocyte/ macrophage, which presents with various histologic features probably due to the influence of cytokines. Non-Langerhans cell histiocytoses are classified according to the predominant mononuclear (vacuolated, spindle-shaped, xanthomatized, scalloped, and oncocytic) and/or multinucleate (Touton, ground-glass appearance, Langhans, and foreign body) histiocytic cell types. Variable mixtures of these cell types produce common polymorphous patterns with prominence of vacuolated, spindle-shaped, and xanthomatized histiocytes in juvenile xanthogranulomas and of scalloped and oncocytic histiocytes in adult xanthogranulomas. Rarely, unusual monomorphous reaction patterns are observed: mostly vacuolated histiocytes are seen in the mononuclear variant of xanthogranulomas, (early benign cephalic histiocytosis, and generalized eruptive histiocytoma. Xanthomatized histiocytes predominate papular xanthoma and rarely xanthoma disseminatum, whereas spindle-shaped histiocytes are evident in spindle cell xanthogranuloma and progressive nodular histiocytosis, scalloped histiocytes are evident in most cases of xanthoma disseminatum, and finally oncocytic histiocytes are evident in reticulohistiocytoma and multicentric histiocytosis. Immunohistochemical, ultrastructural, and clinical findings can rationally be adjusted to this unifying concept of non-Langerhans cell histiocytoses. The time course of lesions, the age of the patients, and the presence or absence of underlying internal diseases are, or may, at least partially, be related to and thus explain variations on the theme of the non-Langerhans cell histiocytic reaction.

Abstract
Of 291 immunosuppressed renal transplant recipients (RTRs) with surviving allografts attending the Royal London Hospital, 171 patients (59%) were found to have warty keratoses. On histological analysis, the lesions in 50 patients (17%) showed partial-thickness dysplasia, and 34 (12%) had one or more invasive squamous cell carcinoma (SCC) and/or one or more in situ SCC or full-thickness dysplasia. We examined the claim that squamoproliferative lesions in RTRs possess distinctive histopathological features that differ from those of similar lesions occurring sporadically in the nonimmunosuppressed population. We compared 40 squamoproliferative lesions from RTRs with 40 matched squamoproliferative lesions from nonimmunosuppressed patients; lesions were coded and their source was unknown to the assessors. Two dermatopathologists independently assessed the cases and gave scores for 11 histological features that have been reported to be characteristic of such lesions in the immunosuppressed population. These included a warty architecture, koilocytes, and multinucleate giant cells. Using these criteria, it was not possible to distinguish lesions of immunosuppressed patients from those of immunocompetent people.
